most have an idle stop screw thats adjustable with a phillips screwdrivewr or a nutdriver head..need to adjust this to between 750-800 minimum..your oil light will go out and proper rpm on the alternator will be achieved..

Hi, this is Shaun again. The answer is the same for a 24v DOHC. Coolant systems are pretty simple and haven't evolved much with different vehicles and motors. It's pretty much the same process with all vehicles.

EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR.

Symptoms: You may notice drivability problems such as pinging (a.k.a. pre-ignition knock) when the engine is under load or the vehicle is at higher speeds. There may also be other symptoms.

Causes: A code P0401 most likely means one or more of the following has happened: * The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced * There is a blockage in the EGR (tube), most likely carbon buildup * The EGR valve is faulty * The EGR valve may not be opening due to a lack of vaccuum

Possible Solutions: In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit. * Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open * Clean out the EGR valve and/or tubing to remove deposits * Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model) * Replace the DPFE sensor (with a good quality / OEM one) * Replace the EGR valve

That is the (Differential Pressure Feedback Exhaust) - e.g. EGR Valve. You shouldn't have any trouble finding it. There is usually a metal tube from the exhaust manifold going to it,as well as one or two vacuum hoses.
It has to also, direct exhaust gas into the intake,so there is your key.

On 3.0L OHV engines, the oil pressure sensor is located on the left
side of the engine block above the flywheel. On 3.0L DOHC engines the
sensor is located on the left side of the engine block above the oil
filter. On 3.4L DOHC engines the sensor is screwed into the oil filter
adapter. The oil pressure sensor operates the oil pressure warning lamp.
